一,如何通过spring的配置文件自动生成表(不是通过hibernate.cfg.xml,这个配置文件我已经删了)
二,看下面一个在spring的配置
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="packagesToScan">
<list>
<value>com.jxszkj.entity</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hbm2ddl.auto">create</prop>
</props>
</property>
</bean>
我该如何知道有哪些hibernateProperties可以配置?查哪个文档?
我查过spring的index和annotation文档,并未查到关于这个配置的详细信息(有事例,但事例只列举了hibernate.dialect,hibernate.show_sql这个两个配置)
恳请指教。

自动建表最好用update, update是第一次建,以后更新, 你create的话每次都会建关于Spring集成hibernate的配置, 应该找Spring的官方文档.!回答完毕

楼主问了两个问题
一,如何通过spring的配置文件自动生成表(不是通过hibernate.cfg.xml,这个配置文件我已经删了)
你的回答:自动建表最好用update, update是第一次建,以后更新, 你create的话每次都会建
就好比人家问你是男是女,你回答说:我不是畜生。
这不是答非所问是什么?
二,楼主已经说了,已经查过spring的index和annotation等相关文档,而苦于没找到相关信息。
你的回答:LZ,hibernateProperties配置信息当然是找官方文档了.!
这个文档提供的是关于jdbc连接的一些配置信息,而楼主要查的是hbm2ddl.auto等的具体使用方法。
自己不懂,还在这装B,装B还不够,还恼羞成怒,摆出自己一副“专家,教授”的样子,对别人指指点点。
送你一句话:莫装B,装B招雷P。
好了,回答两个问题。
一
如果不用hibernate的配置文件,无法实现根据实体类自动生产表。
spring虽然有<prop key="hbm2ddl.auto">create</prop>这个配置,但这个配置并不能真正起到作用,当用spring配置的sessionFactroy做实体类的持久化的时候,系统会抛出异常:没有表可以 插入数据。
二
有一个名为:Hibernate_3.2.0_符合Java习惯的关系数据库持久化_zh_CN.chm
的文件,非常方便实用,LZ可以去下载。
脑袋有点不清白吧?
<prop key="hibernate.hbm2ddl.auto">create</prop>
改成
<prop key="hibernate.hbm2ddl.auto">update</prop>
是<prop key="hibernate.hbm2ddl.auto">
